I recommend Gwangsan Mirae Children's Hospital in Unnam-dong.

When raising a child, there is one children's hospital you go to.

You'll probably be there. My kids always get sick a lot during holidays or early mornings on weekends. The hospital we regularly go to is Gwangsan Mirae Children's Hospital. My kids get better from colds there. The nurses are also very kind and helpful when it comes to IV drips.
